Unfortunately it was someone like you that I was actually expecting to have a good intelligent answer...


I’ve said my piece on this subject many times on different posts. My cars are drag race only so I don’t have to deal with the street driving, street behavior issues. All I’ve heard during most of my 44 years of engine building is quench, quench, quench. Meanwhile my W2 headed engine and Edelbrock headed engines were both open chamber heads with below deck flat top pistons. Both easily ran 9’s. I don’t always go by the book.
